Quizplus · Accepted Answer

The most effective scattering of sunlight occurs at short wavelengths, such as blue and violet. This occurs because blue light has a shorter wavelength and higher frequency than red light. As sunlight enters Earth's atmosphere, the blue and violet components of sunlight scatter more than the other colors because air molecules scatter short wavelength light (blue and violet) more effectively than long wavelength light (red and yellow). This is known as Rayleigh scattering, which is responsible for the blue color of the sky during the daytime.
